The mens shed has picked up two of these Atkins grinders so a brought one home to play with over easter.
The other one is in slightly better shape and was sort of working so I left it at the shed, but this one had a missing starter so I have no idea if it runs.
The spindle turns very smoothly without the belt which is promising.
With the stand being made out of between 12 and 16 mm thick cast iron (:oo:), these things weigh much more than first appearances.
The motor is 3P 1HP, 2850 RPM and it sits at the very bottom of the base.
Combine that with the weight of the base and this gives it excellent stability.
A long belt runs between 2 two speed pulleys that when combined produces pulley ratios are rather odd, 1.1 for one pair and 1.4 for the other.
The 1.1 x 2850 = ~3000 RPM (thats OK) t'd the other would be near 4000 RPM, seems rather high.
There is a sign on the spindle cover that says to only use the higher speed when the wheels wear down to less than 8"
As you can see it needs some TLC - a goof project while SWMBO is off with her horses over the easter break.
